Basic Meta-Model (BMM) vLANG 1.0.0

An open computing environment requires a computable representation of its own models. This representation can be used for reasoning about the models, performing validation and consistency checking, building software and generating documentation.

This document describes the Basic Meta-Model (BMM), a model of object models. It may be considered as an approximate replacement for the UML XMI (UML XML metadata interchange). It is human-readable and writable and supports generic types (open and closed), container types and multiple inheritance.
